Selfie Alert: There were lots of Instagram ops at Charlotte Ronson's dinner party last night. Held on the roof of the Gramercy Park Hotel, the intimate fête boasted a photo booth, a phone-charging station, and a roving pink Fujifilm instant camera manned by the designer herself. And then there were the props—a series of sunglasses created by Ronson and Vogue Eyewear that absolutely everyone tried to steal.

(This being a Charlotte Ronson party, "absolutely everyone" included rogue starlets like Taryn Manning, designers such as Shoshanna Lonstein Gruss, and a few members of her boldface family: mom Ann Dexter-Jones, step-dad and rock star Mick Jones, and little sister Annabelle Dexter-Jones, who still serves as the model for Ronson's collections.)

And then there was Eva Mendes, the face of Vogue Eyewear who collaborated with Ronson on the final designs. We spoke with the actress about her new gig, her sunglasses collection...and her mom!

Your New York & Company collection has a lot of advertising.

I'm sorry! I have to apologize for that, I'm sorry. You have to see my mug every day.

Don't be sorry! Your Calvin Klein billboard was right by our office—and it motivated us to go to the gym every day!

Well, my mother thinks the New York & Company one is better! She's like, "Thank goodness my daughter has clothes on now."

You were the inspiration for Charlotte Ronson's new sunglasses. How did she do?

They're excellent! I was so excited when I saw the sunglasses, because she managed to make something really feminine that's not precious. And I love things that are ultra femme but not precious, and she's just so cool that she gets that idea exactly.

How many pairs of sunglasses do you own?

I think I have about 80 to 100 pairs of Vogue Eyewear sunglasses in the house. That's a lot, right? But it's not too ridiculous.

But where do you put them? Oh my gosh, do you have a sunglasses room?

One can dream! One can dream, huh? But no, actually, I have them all in a not-very-glamorous box, so I can just grab and go.

Please give some advice to ELLE.com readers. How can we not lose our sunglasses?

Oh, I'm the wrong person to ask. I lose them all the time. They're the first things to go, right? The glasses! That's why I have a box of a hundred of them in my house!
